RFC-023: ENFORCE Broadcast — Ephemeral Distributed Enforcement for Governed Autonomy — 17. Supersession

AIGP Specification › RFC-023: ENFORCE Broadcast — Ephemeral Distributed Enforcement for Governed Autonomy › 17. Supersession

17. Supersession

ENFORCE signals may supersede prior signals.

A superseding signal MUST include:

new signal_id
superseded signal_id
issuer authority
reason
timestamp
TTL
D-DNA binding

Example:

supersedes:
  - ebs.sar17.000817
reason: hazard_boundary_updated

If two valid signals conflict, the supersession chain and priority rules determine which applies.

If supersession cannot be verified, actors MUST apply the safer valid state.
